Customer Reviews for Tenacity Herbicide

Chat team was super helpful in advising me on products/seeding combo. Applied Tenacity 2 weeks ago. It took 7 days to see any changes, but getting ready to re-apply as per instructed and so happy with the results. The clover that has been lingering for years is gone!...the weeds too. Thanks!

After reading the instructions, I mixed the herbicide at double the strength suggested and my wife applied the mixture to some grasses she wanted to remove from our landscaping. Nothing died.

After trying for 5 years to control the weeds in my yard, this product appears to be the first that's really working. The weather hasn't been cooperating, so I haven't had a chance to use it on my entire yard, but in the areas where I've sprayed this, the weeds have turned white and then disappeared. Great product AND great service from the provider. Thanks!

This stuff is legit. Had some extremely stubborn crab grass and it knocked it out like a dream. Followed the directions and it worked great. Killed all the other weeds as well. Used some blue dye to mark the areas I sprayed and it was a big help. Applied it three weeks ago and the crab grass is non existent. Excellent product.

Almost 2 weeks now and some slight discoloration of the crabgrass stalks. Some heavy duty stuff at 1 tsp per gallon of water. Using on centipede and very hopeful for success. Instructions say it'll kill post emergent poanna as well. I haven't tried that yet, waiting on Summer heat to kill it and then use pre emergent next year.

Did fairly well on chickweed and ok on dandelions. Probably would have performed better in late summer early fall with a follow up in spring. My yard is too large to handle the weeds and afford the ability to do so

I almost went with 5 stars but I just dont know enough yet. It will be 2 weeks tomorrow from the first time that I used Tenacity. After 1 week, my crabgrass began turning white. I just noticed yesterday that the clover weeds had begun turning white. I have some other weeds in my grass (not sure what they are) but i don't think I've noticed them turning white yet. This is only my first application and I used dish soap as a surfactant. I am thinking about investing in a true surfactant for my second application next week, we will see how it goes.

Recently I decided to over seed my old beat up and tired lawn. Before I bought my seed I went ahead and applied a blanket treatment of tenacity only a pre-emergent with no surfractant. During the time of application I did notice weeds growing due to it being early spring in the Midwest, but that was not of my concern. My plan of attack was to overseed to punch out all the crabgrass and wild weeds. As I was prepping the lawn for the seeding two weeks later to my astonishment and to my surprise I noticed all my crab grass and wild weeds were all white and dead. Pretty much all of it was killed with out a surfactant. My main purpose was to use it as a pre-emergent but it actually works as a post to merge it with out surfractant

Bought to help control and identify poa triv. After spraying results took about 2 weeks to appear. Product is working and has not harmed turf. Also plan to use when seeding. Lawn is cool season tttf for reference. Do my own was awesome as always and product arrived quickly even with the current situation. Thanks.

I really wanted to like this product, but after my second year of using it I find it to be mediocre. I have followed the directions exactly including using surfactant, and my experience is that 1) it partially kills off some weeds, but leaves others unscathed (it's totally ineffective against clover), and 2) it takes forever. Do you like to wait six weeks for a weed to die? I don't. My dandelions are dying off, but the product works so slowly that they have had time to flower and seed. My lawn has the same or more weeds after two seasons on Tenacity than it did in the past using cheap and fast Weed-B-Gon.

It really works on tough weeds. I am satisfied with this product. I like that it in small bottle and there is enough for many applications.

This stuff is the real deal! It works as described. I have been very impressed with it on my lawn.

Be patient, 3 weeks later some items like clover are still turning white and dying their slow death. I mixed it in with my liquid fert application, plan to repeat this with each monthly application. Insanely concentrated, I used .5tsp (yes teaspoon) per 1,000sqft.

Works great, and cheaper than we can find locally. Doesn't take long to receive after preserving either. Have been very satisfied with everything we have purchased from this company. Highly recommend!

Tenacity works exactly as advertised. Follow directions! I used it on a lawn filled with Nimblewill. Worked great!

After killing my whole yard and replanting only for the weeds to once again take over. I did some research, and learned about Tenacity. It does what it says. It kills the weeds, and leaves the grass. Can be used as a pre or a post emergent. Allowing you to overseed for a full weed free lawn. I love it!

I applied Tenacity as directed and I am getting the results as promised. My weeds have turned color and are dying after 2 weeks. Thank you. It is expensive but I think it is worth it compared to several other products I have used with unsatiafactory results.

Easy to understand mix ratio. Effective weed treatment.

I mixed and sprayed the day I received. I was a little discouraged as it rained about 3 hours after I put down. I waited a few days and thought about applying again but I did not have the time (right in a pandemic no time). However about two days later the crabgrass started turning white. Holy cow. ????. However... get the dye! I missed a few spots.

Thought I would give this a try reviews sounded good. Made one application waited two weeks seen very little effect. Applied another application but a little heavier sprain making sure the crabgrass was wet. Now 2 weeks later the crab grass is starting to turn white appears the product is working.

This was my first time spraying a high end herbicide like this. I spot sprayed my crabgrass and a host of broadleaf weeds. It has been two weeks now and can see they are ALL dying now. It did take a week to start showing signs, but now all the weeds sprayed are bleached and will be gone soon. I love the low use rate of this product and how effective it is. Oh some of the crabgrass sprayed was in the 3 or 4 tiller stage and this was still effective.

The hole experience was good. The web site was easy to use, and provided the information I need to make my Selections. Product price and shipping was at a good range. Delivery time good.

Very satisfied with this product. Worked better than expected. I had been using Scott's products for a long time and will not go back to there product.

Did two applications per instructions with NIS 2.5 weeks apart. So far the dandelions are nearly gone and the chickweed is really stunted. Unfortunately only the very young clover has died off and even more clover has grown in the last 3 weeks. Any advise would help here.

Tenacity worked really well but I did not see any results until after a couple weeks.

I purchased Tenacity to kill post emergent Poa Annua and other hard to kill weeds. Worked great.
